Goldfish need a lot of space. They don’t like those silly little goldfish bowls you see at the carnival. You need a rectangular fish aquarium.

The fish aquarium has the right type and size of opening so that there is plenty of surface space coming into contact with the air. The little fish bowl does not have enough of an opening or space coming into contact with the air. The large aquarium will increase the amount of oxygen in the water.

Fish need air. They breathe different than we do but they still need to breathe. We will learn how fish breathe and swim latter on! We will do an experiment to find out how fish can swim to the top of the tank and the bottom of the tank. A fish aquarium can also be called a fish tank.

Did you know that a goldfish can live to 25-years if you take good care of the goldfish?

You will need certain items at your home before you can bring a fish home. You will need the fish aquarium, food, filtered water, water filter, and testing kits.

Your fish will like a place to hide, gravel, and plants. Fish are much smarter than people give them credit, and they need new and exciting things too.

The water filter is to keep the water clean – fish can get messy just like kids. It will filter out the nasty stuff the fish leave behind.

The filtered water is to make sure there is nothing in the water that can hurt the fish, like heavy metals and chlorine.

Testing kits will test the water to check for ammonia and nitrites. We will have a whole new section on water testing.

Planning Ahead
At first, you will only want a few fish. Later on, if your aquarium is big enough you can add some more fish. But, never more than one 2-inch fish per two gallons of water. So that would be five fish in a 10-gallon tank, or ten fish in a 20-gallon tank.

When you see the little boy thinking, you know we still have more to learn before we buy our fish.

Soon you will need an empty plastic soda pop bottle for a fun experiment. Ask your parent or guardian if you can have a plastic soda bottle.

We still have a lot to learn about fish before you buy and bring your fish home. In the meantime, would you like to color some pictures of fish? Coloring is fun!
